A massive explosion has rocked a fertilizer plant near Waco, Texas. Rescue crews are on the scene as a number of injuries have been reported, according to local affiliate KWTX. Several buildings are thought to have been destroyed.

There were accounts of people trapped in a nearby nursing home, which had been damaged, and residents stranded in an adjacent apartment building. Initial reports indicated that at least five victims were in critical condition.

The explosion occurred around 7:50pm local time in the town of West, north of Waco. A fireball of nearly 100 feet high has been reported along with a massive power outage.

A large swath of West, Texas was “leveled” in the explosion, according to WFAA-TV Dallas reporter Jason Whitely.

Nine emergency helicopters were reported to be en route to the local high school. Emergency officials were also trying to evacuate a neighborhood near the site of the explosion. Hospital officials told CNN they were anticipating as many as 100 victims.

Police officers were witnessed transporting the injured in their squad cars.

At least 10 other buildings are on fire, including the town middle school, according to other media outlets. Every available ambulance had been dispatched while fire crews from neighboring areas have rushed to the scene.

An emergency responder requested help over local radio with a “major collapse” on a second floor where children were thought to be trapped.

Multiple commenters on RT’s story reported feeling the blast from their homes, which were located as much as dozens of miles from the fertilizer plant.
